Our improved shell blank sewing device is preferably built in batteries; that is to say, with several sawing units mounted on one main free e. In the accompanying drawings we have used the reference numoral 10 to indicate generally the base of the main frame oi our machine. In the type oi machine shown, the hose 10 is provided with suitable vertical sockets 11. for receivthe lower ends oi supporting posts 12. There is one post 12 at each corner, one in tront and one in rear near the middle of the main frame. The posts 12 have reduced portions 13 received in the sockets 11 and terminating in the screw-threedec ends 14?- on which are nuts 15 (Fig. 1).

Our machine includes the table 16, hzwing; on its under su'ftace suitable sockets 1'? which are screw-three ded to receive the screw-threoded upper ends of the posts 12.

Supported on the table 16, near the opposite ends thereof, are upright posts 18, one of which onlv is shown. Near the middle of the table, from end to end, are two spaced posts 19. The posts 18 and 19 are provided with aligned bearings 20, in which, in bushings 21, rotatebly received the ports of :1. two-pert sew shaft 22. The ends of the parts of: the shaft 22 are adjacent to each other midwav between the two uprights l9. and slidably but nonrotetablv mounted on said ends is a belt pulley 23.

Mounted on the shaft 22 are several groups of saws. which are all alike. Therefore only one group will he described.

The shatt members 22 are provided with akev way 2 1. Mounted on the shaft 22 and spaced from each other is a series of shell cutting saws 25, which also have slots to receive a key. The saws" 25 are spaced apart by spacer sleeves 26, which are locked to the shaft 22 by means of a key 27 received in the key way 24, whereby the saws and spacer sleeves and shaft are locked against relative rotation.

Just outside each endmost saw .25 is a sleeve 28, similar to the sleeves 26, eiic'ept that thesleeve 28 has mounted in it a set screw 29 extended intoagroove 3,6 in the shaft 22 for locking the saws against sliding moyement on the shaft. I j I In this connection it may be mentioned thatitisdesirable in many instanceslto saw shell strips or blanks different w1dths, and therefore it is necessary that the saws at times be spaced different distances apart. This is accomplished by using dilterent spacer sleeves 26 and lockingsleevcs 28. h

Rotation is imparted to the shaft members 22 and to the saws thereon through the belt pulley 23,- which may be operated from any suitable source otpower. j

Mountedon the rear posts 12, between the table 16 and the base l0, are forwardly extending bearing brackets 31, which support the e-am shaft 32. Qn the cam shaft 32 is a cam. 38 :tor each set of saws 25 and shell holding table. The shaft 32 is preferably provided at one end with fast and loose pulleys 3i and 35, the functions of which are obvious.

Directly above each cam 33 and above the table 16, is what for convenience we will call the raising table 36, which is supported on a vertical shaft extended through a suitable bearing 38 in the table 16, and carrying at its lower end a yoke 39 in which is mounted a roller 40 which eoacts" with the cam The raising table 86 has near its sides, guide ribs d1 extending fore andaft in the inachine and having their adjacent faces beveled from their upper ,edges downwardly and away from each other, as illustrated at 42 Figure 1. I

Extending downwardly from the bottom of each raising table 36, and spaced torwardly from the shaft 37 of such table, is a guide rod 43 which is slidably mounted in the table 16 (see Figs. 8 and 1).

It may be mentioned in this connection that/the yoke 39 provided with a shank at which screws into the lower end of the shaft 37, so that said yoke may be quickly and easily removed for repairing or replacing its roller 40.

Supported on each raising table 36 is what we may call a sliding table 45, having at its forward end a handle 46. The sliding table 45 has downwardly extending ribs or guide members 4L7, adapted to coact with the guide ribs ll, for the slidable mounting of the table 45 on the table 36.

Between one of the ribs 47 and the adjacent rib 41 of the table 36 is an ordinary removable dove-tail gib' 36.

In the table 45 is an elongated slot a8, shown in Figure 8. Mounted inthe table 36 is a stop bolt or pin 49, which projects into said slot 4:8 and limits the tore-and-alt sliding movement of the table 45 with relation to the table 36.

Uri the left side of the table 45, as illus trated in Figure 9, for instance, are laterally projecting arms 50 forming bearings which receive a shaft 51.

The table 45 has at its sides upwardly extending; walls 52, and at its front a similar wall 53, with. which the handle 46 is connected. Normally resting upon the upper surfaces of the walls 52 is what we shall call the shell grid plate 54, having a series of spaced elongated slots 55 which register with the respective saws 25 so that when the table 45 is raised the saws 25 may project into the slots 55 and into the space below the grid 54:. The grid 5% has at its left side, illustrated in Figures 9 and 10, downwardly extending ears 56 which form bearings for the shaft 51 and provide means for hinge dly mounting the grid 5% on said shaft.

Near the rear end of the grid 54- said grid is formed with a substantially V-shaped shoulder 57 shown in Figure 8, and in dotted lines in Figure 9.

Mounted on the shaft 51 beneath the left hand side 01 the grid 54:, isa movable trig ger device 58 which in its normal position has an upper substantially flat surface 59 which rests against the under surface of the grid 54 and is provided with a downwardly hanging arm 60 adapted to engage a cam hereinafter referred to. The trig"- ger device 58 has a shoulder 61, so arranged that when the arm 60, as shown in Figure 10, is engaged and pushed toward the right, said shoulder will engage the under surface of? the grid 54; to the right of the hinge line of said grid, for thereby tilting said grid upwardly and toward the left. The trigger device 58 has the curved surface: 62, so a1- ranged that when the arm 60 is pushed toward the left the curved surface 62 will slide under the grid 54; without afli'ecting said grid.

(in the table 36 is a laterally extending flange 63, shown, for instance, in Figure 9, having at its outer edge an upwardly extending cam 64 standing in the path of travel of the arm 60 when the table 45 is shoved fore and aft in the machine.

The parts just described are so constructed that when the table 45 is pushed rearwardly toward. its position beneath the saws, the arm 60 will engage the cam 64 and be swung to the left, but the grid 54 will be not at fected. On the other hand, when the table is pulled forwardly in the nieohine, the arm will engage the righthencl surface or" the cam i l and be shoved toward the right for causing the shoulder 61 to engage and raise the griol 5 1, for tilting; it npwertll g' so as to cause anything thet in, rest upon it to slide toward the left The grid is shown in its tilted position in Figure 8 dotted lines.

At the front of the main teble LU nnl at the left of each of the shell holding table clevices, is a suitable opening;- 65 tlirou which the contents of the grid ni v be Eisolizu'getl into it chute 66 ancl from it suitable container 67 (see and 9).

Will be understood that when at shell is placed on the grid 54: it may be shoved remrnnrclly until it engages the shoulder 57. For then holding the shell on the grid. have provided the following shell holcler finger device:

A strip or plate 68 is hinged, as on a pintle 69, at the rear part of the table 4-5, and securecl to said plate 68 is e plurality oi forwardly extending, sgocecl, shell gripping fingers '20, which preferably curved upwardly at their cent *al PQITEIOHS, as illns trsterl in Figure 8. These fingz ers sgecec apart so that the spaces between tliem ister with and COZ'TUSPOIHJE in width to the slots 55 so that when the shell llOldlll? a 3 tables ere ieisecl the between the fingers 70.

This pawl member has on the forward side or seid projection, a beveled edge 98. The pawl 96 is normally held at the rearward position of its movement by means of e spring" 99.

in the form of the device shown in F' tire l3, l4; and 15. when the table l5 is in any of is forward. positions Oil movement the pin 91 errrgngzes the under surface of said table for holding the clutch out of engagement. When, however, the table 4:5 is pushed resrwerdly tow; sewing: iosition. the pin 91 engages theproicction 97 on the end of the pawl and forces said. pawl torwerdlv in its slot until the oin 91 registers with the rearward end of the slot, whereunon the s r-cinewill :i orce the pin upwardly into the slo and the "carts will assume the position shown in Figure 1.41. After the shell holding table has reiscd tor the sewing; operation,2ind has cleared the rod 91 and permitted the pawl to slide reerwerdlv. then when the shell holding table is lowered the parts stand as shown in Figure 13. When the sliding table is pulled forwsrdlv again. the un oer end of the pin 91 will slice over the beveled edote 98.

It will thus be seen that with both of the terms of the clutch controlling mechanism, we have provided means wherebv the shell holdingmembers are disconnected from the we have shown forward end an elongated slot sli'le le e vi 943 osrn shaft encent after the slideble table is moved reerwerdlv to sewing position.
